ARC-LAMP.

Specification of Letters Patent.

Patented Oct. 13, 1914.

Application filed March 6, 1911. Serial No. 612,639.

T 0 all whom it may concern:

Be it known that I, HARRY E.-R1NGE, a citizen of the United States, residing at WVyncote, in the county of Montgomery and State of Pennsylvania, have invented certain new and useful Improvements in Arc-Lamps, of which the following is a specification.

This invention relates to are lamps for moving picture machines and has for its object to provide a means by which an electric current may be conveyed to the carbons without danger of having the uninsulated conveyer come sufliciently near any other metal than the carbon holders to cause danger of fire, wires burning off and breaking of holders.

With the above andother objects in view, I have invented the device illustrated in the accompanying drawings in which,

Figure 1 is a perspective view embodying my improvement, Fig. 2 isan enlarged detail of a contact member, Fig. 3 is a top plan view of a carbon holder and contact member, Fig. 4 is a transverse sectional view taken on line AA of Fig. 3, Fig. 5 is a contact member taken partly in section showing a conduction wire secured therein, Fig. 6 is an edge view of Fig. 3, Fig. 7 is a. perspective detail of a wedging member.

Referring to the accompanying drawings 1 is a support which is mounted on a stand in a lamp house, (not shown). On this support is a guide member 2 through which the racked bars 3 and t ass. The member 5 is provided with a pinion (not shown) on its inner end by means of which either one of the bars 3 or 4 may be raised or lowered and 6 is'an adjusting member. On the outer ends of the bars 3 and 4 are insulated supports 7 and S which hold the carbon holders 9 and 10. These holders are provided with openings 11 through which the carbons 12 and 13 pass. 1

Secured to the clamping members 9 and 10, which are preferably made of brass, by means of thumb screws 14 and 21, are contact conducting. members 15 and 16; 15 being straight and held to the lower member 9 by means of its bifurcated end 17, which engages the screw 14, 16 being bent to avoid the other parts and so that the electric wire held in the socket 18 thereof will be direct ed down toward the door (not shown) of a lamp house. The member 16 is also provided with a bifurcated end 20 which engages screw 21. i

The sockets l8 and the members 15 and 16 have their inner ends reduced so that the stripped conducting wire 23 will fit snugly therein and the screws 21 are adapted to tightly clampthe stripped conducting wires to prevent them from slipping from their sockets.

The members 9 and 10 are provided with contact arms 25 and 26 upon which the contact members 17 and 20 are adapted to seat. The device is so arranged that the exposed electrified parts are held away from any other conducting or inflammable material, thus eliminating the danger of fire caused by the exposed parts, which danger is at the present time so prevalent.

The arms 14' are integrally formed upon the carbon holders and are spaced laterally from the contact arms 25 and 26. The insulating supports 7 and 8 of which one is carried at one end of each rack bar 3 and 4 are secured to the arms 14. The contact arms 25 and 26 form ofisets disposed at right angles to the arms 11 for the reason that when the cord tips are secured upon said contact arms they will at the same time be spaced over said insulating sup orts and away from the rack bars, in accor ance with the stated principle of my invention.

The holders 9 and 10 are provided with a slot in which the clamping member 27 is slidable by means of the screw 28 having a swivel 29 which operates in the slot 30 to' move said member 27 laterally.

I claim and desire to secure by Letters 7 Patent A device of the kind described comprising two bars, means for separating and advancing said bars, two carbon holders, an arm formed upon each carbon holder, an insulating part at one end of each bar secured to one of said arms, an integral arm formed laterally and extending upwardly of each of said first-named arms, each of said laterally-extending arms having a flat top, terminal tips secured upon said upwardly-extending arms, a fork formed upon each of said terminal tips, each of said forks arranged to bear upon the flat top of one of said arms, thumb screws engaging Said arms and arranged to bind against said fork and means on the arms co-acting with the forks and thumb screws to prevent relative movement between the tips and arms in the plane of the top of the arm.

In testimony whereof I afi'lx my signature 1n presence of two wltnesses.
